The utility model belongs to the technical field of diesel purification, and particularly relates to a novel SCR purifier for a diesel vehicle. The gas-liquid separator comprises a cylinder body, a gas inlet pipe and a gas outlet pipe are arranged on the cylinder body, and one end of the cylinder body is connected with the gas inlet pipe. In the using process, gas enters the urea spraying piece through the gas inlet pipe, harmful gas and high-pressure urea spray sprayed by the urea spraying piece are mixed through the urea spraying piece, reduction reaction is accelerated, and then the gas enters the cylinder body; the multiple catalytic capture assemblies are used for carrying out oxidation and reduction reactions on gas, harmful gas CO, SOF and THC are oxidized into CO2 and H2O, NOx is reduced into N2 under the action of a reducing agent, carbon particles are captured, redundant ammonia gas is oxidized into N2 gas, finally, treated clean exhaust gas enters the atmosphere after being subjected to noise reduc
